Week 4( part 2)

Finally week 4 has been ended.In this week ,we learnt about the communications medium for networking and also learnt about the types of networking .
Networking communication medium:

• Communication channel 
• Network media
• Physical media 
• Physical medium 
• Digital communication 
• Wireless Networking

Now I am going to discuss about the types of networking.There are three main types of networking.
Types of networking :

LAN (Local area network)
WAN(Wide area network)
MAN(Metropolitan area network)
LAN(Local area network):
Local area network is the group of two or more computers, physically close together usually in the same building that are linked to gather to each other.LANs can contain devices other than computers, For example, Printers,Print servers,Storage devices,etc

WAN(Wide area network):
 A network that spans a relatively large geographical area. Typically a WAN consist of two or more local area network.Computers connected to a wide area network are often connected through public networks, such as the telephone system.

MAN(Metropolitan area network):
A metropolitan area network is a computer network that usually spans a city or large campus.A MAN usually interconnected a number of local area networks (LAN) using a high-capacity backbone technology,such as fiber-optic links, and provides up link services to wide area network and the internet.

At first , I was so confused between three main types of Networking but now I have alot of knowledge and understanding about them.
